An efficient radical cyclization of N‐(4‐methoxyphenyl)‐N‐methyl‐3‐phenylpropiolamides with 1‐phenylcyclopropan‐1‐ols has been achieved using Na2S2O8 to produce azaspiro[4.5]deca‐3,6,9‐triene‐2,8‐diones. Similarly, the reaction of 1‐[6‐methoxy‐3,4‐dihydroquinolin‐1(2H)‐yl]‐3‐phenylprop‐2‐yn‐1‐ones with 1‐phenylcyclopropan‐1‐ols gives 6,7‐dihydro‐3H‐pyrrolo[2,1‐j]quinoline‐3,9(5H)‐diones.

Na2S2O8促进的自由基环化反应用于合成Azaspiro [4.5] deca-3,6,9-三烯-2,8-dione和Pyrrolo [2,1-j]喹诺酮衍生物

使用Na 2 S 2 O 8生成氮杂螺[4.5] deca-3,6,可以有效地将N-(4-甲氧基苯基)-N-甲基-3-苯基丙酰胺与1-苯基环丙烷-1-醇进行自由基环化。9-三烯-2,8-二酮。同样,1- [6-甲氧基-3,4-二氢喹啉-1(2 H)-基] -3-苯基丙-2-炔-1-酮与1-苯基环丙-1-醇的反应得到6,7二氢-3- ħ吡咯并[2,1- Ĵ ]喹啉-3,9-(5 ħ) -二酮。
